  • the present invention also relates to a compound having an additive and synergistic effect of amlodipine or a pharmaceutically acceptable acid addition salt thereof and an angiotensin receptor inhibitor such as irbesartan or a pharmaceutically acceptable salt thereof.
  • Compounds with additive and synergistic effects can be used to treat individuals with angina, atherosclerosis, mixed hypertension, and hyperlipidemia, as well as individuals, including humans, who have cardiac risk symptoms or signs. Background technique
  • Hypertension is the main cause of coronary heart disease, cerebrovascular disease and renal vascular disease, and it is also the main cause of death and sickness in adults.
  • ACE inhibitors have the following advantages: (1) superior to general vasodilators, When blood pressure drops, heart and kidney blood flow does not decrease. (2) It is superior to calcium antagonists, does not cause water and steel retention, and does not increase heart rate. (3) Better than a-blocker, does not cause orthostatic hypotension. (4) Better than the older generation of antihypertensive drugs, no central role. (5) Better than nitrate drugs, no drug resistance, no liver first pass effect. (6) There is no stopping phenomenon.
  • ACE inhibitors such as non-dose-related irritating dry cough (5% to 20%), fatal angioedema such as pharynx, larynx, respiratory tract, and lung (0.1 to 0.2%).
  • Angll angiotensin receptor antagonists, avoiding the rise of bradykinin, directly blocking the ATI receptor.
  • ATI antagonizes the inhibitor Angll-mediated vasoconstriction, and inhibits Ang II-mediated renal tubular sodium and water reabsorption; inhibits RAS regulation of stress receptor reflexes, increases sensitivity, and inhibits sympathetic excitation Induction of the central and peripheral sympathetic nerves, the difference between ATI antagonists and ACE inhibitors is the blockade of receptor levels, rather than blockade of the ACE pathway.
  • ACE inhibitors are beneficial for blocking Angll, while the increase of bradykinin is not conducive to the production of Angll by chymase;
  • ATI antagonists are beneficial for blocking Angll adverse Angll production, 70% rely on chymase, and 30% rely on ACE.
  • amlodipine an antihypertensive drug, and related dihydropyridine compounds.
  • Amlodipine besylate is disclosed in U.S. Patent 4,879,303, the disclosure of which is incorporated herein by reference.
  • Amlodipine and amlodipine besylate are strong long-acting calcium channel blockers. Therefore, amlodipine, amlodipine besylate and other pharmaceutically acceptable acid addition salts of amlodipine can be used as antihypertensive agents and anti-ischemic drugs.
  • amlodipine and its pharmaceutically acceptable acid addition salts in the treatment of congestive heart failure is also disclosed in U.S. Patent 5,155,120.
  • Amlodipine besylate is currently marketed under the name Norvasc®.
  • Amlodipine has the following structural formula.
  • Atherosclerosis is a condition characterized by irregularly distributed lipid deposits on the intima of arteries, including the coronary arteries, carotid arteries, and peripheral arteries. Deaths caused by atherosclerotic coronary heart disease (hereinafter referred to as "CHD") accounted for 53% of all deaths caused by cardiovascular events. CHD accounts for nearly half of the total annual cost of cardiovascular medicine in the United States (about $500-60 billion) and about 6% of total national medical expenditure. Despite attempts to change secondary risk factors such as smoking, obesity and lack of exercise, as well as treatment of dyslipidemia by changing diet and medication, CHD is still the leading cause of death in the United States.
  • CHD atherosclerotic coronary heart disease
  • Amlodipine can prevent myocardial ischemia in patients with angina pectoris by reducing total peripheral resistance (or afterload), which reduces the heart rate and blood pressure product, thereby reducing the need for myocardial oxygen at any given level of exercise.
  • amlodipine has been shown to block contractions and restore oxygen supply to the heart muscle.
  • amlodipine can increase the oxygen supply to the myocardium by dilating the coronary arteries.
  • Hypertension is often associated with hyperlipidemia and is considered to be a major risk factor for the development of heart disease that ultimately leads to adverse cardiac events. The classification of such risk factors may be due to a common mechanism.
  • patients are generally more compliant with hypertension control than with high blood lipids. Therefore, a single therapy that can treat these conditions simultaneously is beneficial to the patient.
  • Coronary heart disease is a multifactorial disease whose incidence and severity are affected by lipid distribution, the presence of diabetes, and the gender of the patient. The incidence is also affected by smoking and left ventricular hypertrophy (caused by hypertension). In order to significantly reduce the risk of coronary heart disease, it is important to control the entire risk spectrum. For example, attempts to hypertensive intervention have not been shown to completely normalize cardiovascular mortality caused by coronary heart disease. Treatment of patients with or without coronary artery disease with cholesterol synthesis inhibitors reduces the risk of cardiovascular morbidity and mortality.
  • the FraminSham Heart Study (in ongoing prospects for adult males and females) confirms that certain risk factors can be used to anticipate the development of coronary heart disease (see Wilson et al., Am. J. Cardiol 1987, 59). (14): 91G—94G). These factors include age, gender, total cholesterol levels, high-density lipoprotein (HDL) levels, systolic blood pressure, smoking, impaired glucose tolerance, and cardiac enlargement (in ECG, Left ventricular hypertrophy on the echocardiogram or heart enlargement in the chest X-ray). It is easy to program a calculator or computer with a multivariate logic function to calculate the conditional probability of a cardiovascular event. Based on these factors include age, gender, total cholesterol levels, high-density lipoprotein (HDL) levels, systolic blood pressure, smoking, impaired glucose tolerance, and cardiac enlargement (in ECG, Left ventricular hypertrophy on the echocardiogram or heart enlargement in the chest X-ray).

Description

包含氨氯地平和血管紧张素 II受体抑制剂的组合物 技术领域
本发明涉及氨氯地平或其可药用酸加成盐和血管紧张素 II受体抑制剂如厄贝 沙坦等及其可药用盐的药物复方、 含有所述复方的试剂盒以及使用所述复方对患 有心绞痛、 动脉粥样硬化、 混合型高血压和高脂血症的个体和存在心脏危险性症 状的个体、 包括人进行治疗的方法。
本发明还涉及氨氯地平或其可药用酸加成盐和血管紧张素 Π受体抑制剂如厄 贝沙坦等化合物或其可药用盐的具有相加和协同作用的复方, 从而所述具有相加 和协同作用的复方可用于对患有心绞痛、 动脉粥样硬化、 混合型高血压和高脂血 症的个体和存在心脏危险性症状或征兆的个体、 包括人进行治疗。 背景技术
据 WTO估计, 约有 20%成人患高血压,且在确诊病人中,有 75%未能得到有 效治疗。 因高血压死亡者约占心血管疾病的发病率 50%逐年上升, 病残率也呈上 弁趋势, 死亡率居高不下。 据国内临床统计, 血压下降 1.20/0.67KPA, 每年约可 防止 45万人死于卒中。 有研究显示, 血压降低 0.67Kpa, 心血管危险下降 30%。
随着血压的升高, 卒中、 冠状动脉事件的危险性随之增大, 高血压是冠心病、 脑血管疾病、 肾血管疾病的主要致病因素, 也是成人死亡、 病残的主要原因。
临床治疗的目标是采用耐受性较好的药物有效控制血压; 预防或转心、 肾、 脑靶器官的损害; 降低心血管病的死亡率和发病率。 临床常用的抗血压药物中, 20世纪 80年代开发的 ACE抑制剂可说是一类很有效的降血压药物, 在药理学上 ACE抑制剂具有如下优点: (1)优于一般扩血管药, 血压下降时, 心、 肾血流量不 下降。 (2)优于钙拮抗剂, 不会引起水、 钢潴留, 不增快心率。 (3)优于 a- 阻滞剂, 不会引起体位性低血压。 (4)优于老一代降压药, 无中枢作用。 (5)优于硝酸酯类药 物, 无耐药性, 无肝脏首过效应。 (6)无停药反跳现象。
但是, 由于 ACE抑制剂存在着不可克服的不良反应, 如非剂量相关性的刺激 性干咳 (5%~20%), 咽、 喉, 呼吸道, 肺等致命性血管神经性水肿 (0.1~0.2%), 从而促使人们研制开发血管紧张 Π (Angll ) 受体拮抗剂, 避免了缓激肽的上升, 直接阻滞了 ATI受体。 ATI拮抗抑制剂 Angll介导的血管收缩, 同时, 抑制 Ang II介导的肾小管钠、 水重吸收; 抑制 RAS对压力受体反射的调控, 提高敏感性, 对交感神经兴奋具有抑制作用并介导中枢及外周交感神经的加压作用, ATI 拮抗 剂与 ACE抑制剂作用的区别是受体水平阻断, 而非 ACE途径阻滞。 ACE抑制剂 有利于阻滞 Angll ,而缓激肽上升则不利于糜酶产生 Angll ; ATI拮抗剂有利于阻 滞 Angll不利 Angll的产生, 70%依靠糜酶, 30%依靠 ACE。
美国专利 4,572,909 (该文献引入本文作为参考) 公开了用作强效抗局部缺血 和抗高血压药的氨氯地平以及相关的二氢吡啶化合物。 美国专利 4,879,303 (该文 献引入本文作为参考) 公开了氨氯地平苯磺酸盐。 氨氯地平和氨氯地平苯磺酸盐 是强的长效钙通道阻滞剂。 因此, 氨氯地平、 氨氯地平苯磺酸盐和氨氯地平的其 它可药用酸加成盐可以用作抗高血压药和抗局部缺血药物。 在美国专利 5,155,120 中还公开了氨氯地平及其可药用酸加成盐在治疗充血性心衰中的用途。 氨氯地平 苯磺酸盐目前以 Norvasc®的名称销售。 氨氯地平具有如下结构式。

动脉粥样硬化是一种以在动脉、 包括冠状动脉、 颈动脉和外周动脉内膜上不 规则分布的脂质沉积为特征的病症。 由动脉粥样硬化性冠心病 (以下称为 "CHD" ) 引起的死亡占所有由心血管事件引起的死亡的 53%。 CHD占美国每年心血管医药 总花费的近一半 (约 $500~600亿)和全国医疗总支出的约 6%。尽管尝试改变次级危 险因素如吸烟、 肥胖和缺乏锻练以及通过改变饮食和药物疗法来治疗异常脂血症 (dyslipidemia), 但 CHD在美国仍然是最主要的死因。
氨氯地平可以通过降低总外周阻力 (或称后负荷)来预防劳累型心绞痛患者的 心肌缺血, 它可以降低心率血压乘积, 从而降低任何特定运动水平的心肌氧的需 要。 在患有血管痉挛性心绞痛的患者中, 已证实氨氯地平可以阻断收缩从而恢复 心肌的氧供给。 此外, 氨氯地平还可以通过扩张冠状动脉增加心肌的氧供给。
高血压通常与高脂血症同时存在并且都被认为是发生最终会导致不利心脏事 件的心脏病的主要危险因素。 这种危险因素的分类可能是由于共同的机制。 此外, 患者对高血压控制的遵从性通常比对高血脂的遵从性要好。 因此, 能够同时治 疗这些病症的单一疗法对患者是有利的。
冠心病是一种多因素的疾病, 其发病率和严重程度受脂质分布、 糖尿病的存 在以及患者性别的影响。 发病率还受吸烟以及左心室肥大 (高血压所引起)的影响, 为了显著降低冠心病的危险性, 控制整个危险谱是非常重要的。 例如, 已证实高 血压干预的尝试无法使冠心病引起的心血管死亡率完全正常化。 用胆固醇合成抑 制剂对存在或不存在冠状动脉疾病的患者进行治疗可以降低心血管发病率和死亡 率的危险性。
FraminSham Heart Study (正在进行中的对成年男性和女性的远景调研)证实,某 些危险因素可用于预期冠心病的发展 (参见 Wilson 等, 美国心脏病学杂志 (Am. J. Cardiol) 1987, 59(14): 91G— 94G)。 这些因素包括年龄、 性别、 总胆固 醇水平、 高密度脂蛋白 (HDL)水平、 收缩压、 吸烟、 糖耐量和心脏增大 (在心电图、 超声心动图上的左心室肥大或在胸部 X—射线中的心脏增大)。 很容易用多变量逻 辑函数对计算器或计算机编程, 使其能够计算心血管事件的条件概率。 这些基于
5209名参与 Framingham调研的男性和女性的测定评估了布不同随访期内冠状动 脉疾病的危险性。在任选的六年期间内,模型化发病率从低于 1%至 80%以上不等。 但是, 这些发病率通常低于 10%, 并且在男性中很少超过 45%, 在女性中很少超 过 25%。 发明内容

Chem. ), 1986, 29, 1696的描述制备。 基本上只有 S (—)异构体和含有 R(+)和 S (—)形式的外消旋体混 合物具有钙通道阻滞剂活性。 (参见国际专利申请号 PCT / EP94 / 02697)。 R (+) 异构体的钙通道阻滞剂活性很弱或没有。但是, R(+)异构体是平滑肌细胞迁移的有 效抑制剂。 因此, R(+)异构体可用于治疗或预防动脉粥样硬化。 (参见国际专利申 请号 PCT I EP95 I 00847)。 基于上述理由, 本领域技术人员会选择 R (十)异构体、 S(一)异构体或 R(+)异构体和 S (—)异构体的外消旋混合物用于本发明的复方。
本文所用术语 "心脏危险性"是指患者遭受未来的不利心脏事件如心肌梗塞、 心搏停止、 心衰、 心脏局部缺血的可能性。 心脏危险性可用所述的 Framingham危 险性方程进行计算。 术语 "心脏危险性的控制"是指未来的不利心脏事件的危险 性被大大降低。
本发明的化合物通常以含有至少一种本发明化合物以及可药用载体或稀释剂 的药物组合物的形式给药。 因此, 本发明的化合物可以以任何常规的口服、 胃肠 外或经皮剂型单独或一起给药。
用于口服给药的药物组合物可以是溶液剂、 混悬液、 片剂、 丸剂、 胶囊、 散 剂等剂型。 片剂含有各种赋形剂如柠檬酸钠、 碳酸钙和磷酸钙以及各种崩解剂如 淀粉 (优选土豆淀粉或木薯淀粉)和某些复合硅酸盐, 同时还含有粘合剂如聚乙烯吡 咯烷酮、 蔗糖、 明胶和阿拉伯胶。 此外, 润滑剂如硬脂酸镁、 十二烷基硫酸钠和 滑石对于片剂的制备通常也是非常有用的。 相似类型的固体组合物还可用作软和 硬明胶胶囊的填充物; 就此而言, 优选的材料还包括乳糖以及高分子量的聚乙二 醇。 当需要用含水混悬液和 /或酏剂进行口服给药时, 可将本发明的化合物与各 种甜味剂、 矫味剂、 着色剂、 乳化剂和 /或助悬剂以及稀释剂如水、 乙醇、 丙二 醇、 甘油及其各种组合形式进行混合。
本发明的复方还可以以控释制剂如缓释或快速释放制剂的形式给药。 所述本 发明复方的控释制剂可以按照本领域技术人员公知的方法制备。 给药方法可由主 治医师在评估了患者的病情和需要后决定。 通常优选的氨氯地平的制剂是
Norvasc
胃肠外给药可以采用在蓖麻油或花生油或含水丙二醇中的溶液, 以及相应水 溶性盐的无菌水溶液。 如需要, 可将所述含水溶液进行适当地缓冲, 将液体稀释 剂首先用足够的盐水或葡萄糖调至等渗。 这些含水溶液特别适用于静脉内、 肌肉 内、 皮下和腹膜内注射。 就此而言, 所用的无菌含水溶媒很容易通过本领域技术 人员公知的常规方法获得。
制备含有一定量活性成分的各种药物组合物的方法是本领域技术人员已知 的, 或者对其是显而易见的。 参见, 例如 Remington's Pharmaceuticai SCienCeS, Mack Publishing Company, Easter, Pa., 第 15版 (1975)。
本发明的药物组合物可以含有 0.1%~95%的本发明化合物, 优选 1% ~ 70%。 在任何情况下, 用于给药的组合物或制剂均应含有治疗待治疗患者的病情或疾病 有效量的本发明化合物。
由于本发明涉及使用可以分别给药的活性成分的复方来治疗疾病, 因此, 本 发明还涉及将不同的药物组合物以试剂盒的形式合并。 该试剂盒含有两种不同的 药物组合物: 氨氯地平或其可药用酸加成盐; 血管紧张素 II受体抑制剂或其可药 用盐。 该试剂盒含有用于包含不同组合物的容器如分开的小瓶或分开的箔袋, 但 是, 也可以将不同的组合物包含在单一的、 未分开的容器中。 典型的试剂盒含有 用于对不同成分给药的说明书。 当不同成分优选以不同的剂型 (例如口服和胃肠 外)、 不同的给药间隔进行给药, 或者当复方中的某个成分需要由处方医师逐渐 调节剂量时, 试剂盒的形式是特别有利的。 ,: 本发明以下剂量以及所给出的其它剂量是针对体重为约 6¾¾至约 70kg的一般 人类患者的。 本领域技术人员很容易根据患者的病史以及所存在的疾病如糖尿病 确定出体重在 65kg至 70ks范围之外的患者所需的剂量。文中以及所附权利要求书中 所给出的剂量均为每日剂量。
通常, 根据本发明, 氨氯地平的给药剂量一般为约 0.25mg至约 50mg。 优选氨 氯地平的给药剂量为约 0.5mg至约 25mg。本领域技术人员可以理解,氨氯地平苯磺 酸盐的游离碱形式或其它盐形式也可以用于本发明。 对氨氯地平苯磺酸盐的其它 形式或游离碱形式或其它盐形式的剂量的计算很容易通过将所涉及物质的分子量 进行简单的比较来完成。
通常, 根据本发明, 上述血管紧张素 II受体抑制剂以如下剂量进行给药: 厄贝沙坦, 通常约 25mg至约 600mg, 优选约 50mg至约 300mg;
替米沙坦, 通常约 5mg至约 400mg, 优选约 10mg至约 200mg;
缬沙坦, 通常约 10mg至约 600mg, 优选约 20mg至约 300mg。
氯沙坦, 通常约 5mg至约 400mg, 优选约 10mg至约 200mg;
坎地沙坦, 通常约 0.5mg至约 100mg, 优选约 lmg至约 50mg;
本领域技术人员可以理解,上述血管紧张素 Π受体抑制剂的游离碱形式或其它 盐形式也可以用于本发明。 对所述血管紧张素 II受体抑制剂的其它形式或游离碱 形式或其它盐形式的剂量的计算很容易通过将所涉及物质的分子量进行简单的比 较来完成。 具体实施方式
实施例 1 厄贝沙坦、 氨氯地平联合治疗中重度高血压的疗效观察
HOT研究表明, 70%的高血压患者需要联合用药才能达到降压的目标值。 美 国预防、 检测、 评估与治疗高血压联合和会第七次报告 (JNC 7)指出, 大多数高 血压患者需要 2种或 2种以上的降压药来达到目标血压(< 140/90 mmHg=,如果 血压超过目标血压值的 20/10mmHg, 应考虑选用 2种降压药作为初始用药。 我们 选用血管紧张素 II受体 t (ATi )阻滞剂厄贝沙坦(Irbesartan) (由江苏恒瑞医药股 份有限公司提供) 和钙拮抗剂氨氯地平(Amlodipine) (北京赛科药业有限公司生 产)联合治疗中重度高血压, 初步取得良好的效果, 总结报告如下:
一、 资料和方法
按照《中国高血压防治指南》诊断标准, 选择未服降压药或停药 2周以上的 中重度高血压患者(SBP 160及/或DBP 100mmHg), 排队继发性高血压、严重 心肝肾功能损害、 妊娠及哺乳期妇女、 药物过敏者。
入选病人分 2组, 第一组(Ami '组) 8例, 服氨氯地平 5mg—日一次, 4周, 第二组(Irb+Aml组) 10例, 服厄贝沙坦 150mg及氨氯地平 5mg—日一次, 4周。 其中有 6例来自第一组的继续治疗。 在治疗过程中, 按《心血管药物临床试验评 价方法的建议》 的要求, 每 2周测定坐位血压、 立位血压, 询问和观察不良反映, 治疗前后查血糖、 血酯、 肌酐、 谷丙转氨酶、 钾、 钠及心电图。
疗效标准按卫生部制定的《心血管系统药物临床研究指导原则评定》,(1)显效: 舒张压下降 ^lOmmHg并降至正常或下降 20mmHg以上。 (2)有效: 舒张压下降未 ¾ lOmmHg, 但降至正常或下降 10~19mraHg。 (3)无效: 未达到上述标准。 此外, 根据《中国高血压防治指南》降压目标应达到< 140/90 1¾, 计算降压治疗的达 标率, 这也是近年来常用的疗效指标。
二、 结果
1. 单用氨氯地平治疗中重度高血压, 收缩压在 2周时下降 14.2mmHg, 4周 时下降 19.8mmHg, 舒张压分别下降 11.0及 12.8mmHg。总有效率在第 4周和 4周 时分别为 5/8和 6/8,其中显效率分别为 2/8和 3/8,血压达标者 1例,达标率为 1/8。
(详见表 1、 表 3、 表 5)。
2. 厄贝沙坦、 氨氯地平联合治疗中重度高血压, 收缩压在 2周时下降 28.2 mmHg, 4周时下降 33.6 mmHg,舒张压在 2周和 4周时分别下降 15.6和 18.3 mmHg, 总有效率在 周和 4周时分别为 8/10和 9/10, 其中显交往率分别 6/10和 7/10, 达 标率在 2周和 4周时分别 3/10和 6/10。 (详见表 2、 表 3、 表 5)
3. 治疗前后心率分别为 75.8次 /分和 74.2次 /分, 无显著变化。 未发现直立性 低血压、 肝肾功能损害及其他不良反应。 表 1 氨氯地平降压效果

根据初步研究结果
1. 单用氨氯地平治疗中重度高血压有一定效果, 总有效率达 65%, 但显效率 只有 25%, 降压达标者只有 1例, 达标率 12.5%,不能满足大多数中重度高血压治 疗要求。
2.厄贝沙坦、氨氯地平联合治疗中重度高血压,总有效率达 90%,显效率 70%, 达标率在第 2周和第 4周时分别达到 30%和 60%, 疗效显著优于单用氨氯地平。 厄贝沙坦和氨氯地平联合应用, 具有降压幅度大, 达标速度快, 毒副作用小等优 点, 适合中重度高血压的初始治疗。 实施例 2: 厄贝沙坦和氨氯地平联用对自发性高血压大鼠血压
